FP-Studio installation failure

Hi,
I just installed FramePack Studio. I used the pre-defined installer, which did the job quick and well. Pinokio was installed some days earlier, cause I first did some videos with the "native" FramePack.
As I now started FramePack-Studio, I got this blue-screen message:

--- Attention Configuration ---
⚠️ No attention library found. Using native PyTorch Scaled Dot Product Attention.

• For better performance, consider installing one of:
  SAGE Attention (highest performance), Flash Attention (high performance), or xFormers.

Traceback (most recent call last):

My System:
Windows 11 home 64x
GPU: RTX 4080 Super

So what to do about "Torch not compiled with CUDA enabled"?
As said: The native FramePack works well using my GPU-Card.
